In this paper, based on high-dimensional factor models (HDFMs), an approach is proposed for the decomposition and spatial localization of cascading events. The HDFM divides the raw online monitoring data into factors (spikes, indicating event signals) and residuals (a bulk, indicating noises or normal fluctuations). The estimated number of factors is employed as the indicator to detect the occurrence of subevents. In addition, the autoregressive rate of residuals measures the changes in the temporal correlation of noises to track the system's operating state. Case studies verify the proposed approach.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133695438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To better describe the harmonic emission properties of photovoltaic generation system, an equivalent model that can accurately calculate the output harmonic current of photovoltaic generation system is proposed by analyzing the mechanism of harmonic generation of photovoltaic power. Aiming at the problem of harmonics generated by photovoltaic modules and relevant control strategies, the harmonic current expression is constructed by analyzing the mechanism of harmonic generation. As for the harmonics generated by the inverter, the expression of inverter harmonic transfer function considering the impact of external harmonic disturbance and dead-time effect is established. The equivalent expression of photovoltaic output harmonic current is derived so as to establish a photovoltaic power generation harmonic equivalent model. Finally, the validity of the derived model is verified by the emulation.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133909559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The power grid presents the broadband variation of harmonic frequency and weak grid characteristics. The Harmonic current and harmonic voltage interact and generate each other through large power grid impedance, aggravating the risk of harmonic resonance in grid-connected systems. As the critical equipment, the grid-connected inverter should have the ability to fast and accurate grid signal acquisition. If the inverter harmonic suppression strategy has a particular structure and parameters, it will not be able to adapt to the situation of decreasing the harmonic frequency and changing harmonic content, thus aggravating the instability under the weak grid. This paper proposes a broadband adaptive harmonic resonance suppression strategy based on a sliding-window FFT algorithm to solve the above instability issues. The sliding-window FFT algorithm can obtain the multi-harmonic information with changing grid points in real-time at a higher rate. The structure and parameters of the harmonic resonance suppression strategy can adaptively change with the obtained multi-harmonic information, and it does not affect the control characteristics at other frequencies except harmonic frequency. Therefore, the harmonic suppression ability of the inverter under the weak grid is ensured. Finally, the rationalization of the strategy is validated through simulation experiments under two working conditions.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133122038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with traditional lightning current monitoring schemes, this design has many advantages including simple structure and high anti-interference ability. Polarization state of the signal in the OPGW fiber rotates in the direction of propagation due to the magnetic field generated by lightning strong current according to Faraday effect. Accurate tracking of state of polarization can be achieved by analyzing the change of Stokes parameters on Poincare sphere. In the experiment, lightning strikes with a current of 600 kA is successfully monitored by this scheme. Meanwhile, the error of current monitored via the scheme is approximately 1.5% when the interference RSOP is added.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133394997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we propose a blockchain-based virtual power plant structure to conduct DR transactions. In the proposed framework, blockchain technology is used for privacy protection and revenue distribution. Multi-objective optimization model is used to schedule demands for lower bills while maintaining satisfaction. The model is solved by non-dominated sorting genetic algorithm II and the experiments are carried out on the UK REFIT dataset.

Second, by reducing the inrush current with a phase selection closing approach, the power fluctuation in the adjacent unit is suppressed. Finally, an actual nuclear power plant is used as a prototype to build a simulation model to verify the power fluctuation suppression strategy of the adjacent unit.

When there is a fault, transient frequency fluctuation may cause the disintegration of the transmission system. However, the frequency loop control technology is still immature and cannot be used in actual systems at present. Hence, the paper is aimed to explore the transient frequency fluctuation suppression method without altering the traditional U/f dual closed-loop control structure. For the purpose, considering the dynamic processes of both the MMC and the wind turbine, a detailed mathematical model based on the control structure is initially established. And then transient frequency temporal and spatial distribution characteristics are analyzed through simulation based on Matlab/Simulink. Simulation results show that the transient frequency spatial distribution difference is mainly caused by transient current changing ratio, and the dominant factor of the transient frequency temporal characteristics is the PI controller parameters of the MMC.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114859574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
